Short answer:
Overall, an application submitted in February 2015 will most likely be processed based on the current residency requirement, 3/4 years resident-in-Canada.
Best to apply with at least a week or ten day margin over the minimum 1095 days actual physical presence.
Applications made as of the day prior to the new residency requirement coming into force, will be processed based on the 3/4 requirement.
To be "made" the application must be signed, complete, and actually received by CIC by the day previous to the coming into force date. Incomplete applications returned to applicant are not made until the complete application is submitted, regardless of the date signed.
We do not know when the 4/6 requirement will come into force. It is possible that the new residency requirements could come into force by, say, February 1, 2015. But that appears highly unlikely. Even March 1 seems quite unlikely. After that, though, the risk goes up.
A lot of the anxiety can be eliminated if the government will only announce the date at least a month in advance. That would be the fair thing for this government to do, to give at least a full month's notice in advance. Does not affect me (I became a citizen earlier this year), but I prefer my government to be a fair and just government, so I hope there is a reasonable amount of notice. Unfortunately, however, given this government's past behavior, there is no counting on that happening.
Some much longer, related observations:
Section 46 of Bill C-24 prescribes the dates that the various provisions of the Bill "come into force."
There are four subsections, grouping particular provisions to come into force, two of which reference sections of Bill C-24 already in force, two referencing groups yet to come into force.
The provisions prescribing amendments to sections of the Citizenship Act governing the residency requirement (amendments to section 5 of the Citizenship Act, as prescribed in section 3 of Bill C-24) are grouped in the same subsection as the provisions prescribing the replacement of the section of the Citizenship Act governing grounds for revocation of citizenship (replacing section 10 of the Citizenship Act, as prescribed in section 8 of Bill C-24). This is subsection 46(2) of Bill C-24.
My strong impression is that there will be one order by the Governor in Council fixing the date the provisions in Section 46(2) come into force. That is, that the amendments to the residency requirement provisions for a grant of citizenship will come into force on the same date as the new revocation provisions.
The only prescribed limitation on that date is that it could not be made earlier than one day after the day, as ordered by the Governor in Council, the provisions in subsection 46(1) came into force. That happened August 1st, so that prerequisite is satisfied.
In the meantime, earlier this year (late fall as I recall), the Gazette published official notice for a comment period regarding proposals to amend the regulations governing the revocation of citizenship procedures. So that process is formally underway, indicating the government is moving ahead at due speed to get these provisions implemented.
Galati constitutional challenge:
I am quite confident that there is no Court stay against the coming into force of the provisions about revocation of citizenship for certain dual citizens.
There is NO Supreme Court case as yet. Indeed, so far as I have seen Justice Rennie has yet to rule on the Government's motion to dismiss Galati's challenge outright.
Reminder: Justice Rennie is a Federal Court justice . . . thus this case is not even in the Court of Appeals, let alone the Supreme Court.
The Government's argument as to why Galati's case should be thrown out summarily is precisely that these provisions are not yet in force, the suit is untimely, the issue is not ripe for the Federal Court to decide. The other prong of the Government's argument is essentially a standing issue, that any challenge should only be made only on behalf of an individual actually affected by the statutory provision.
I do not know how Justice Rennie will decide the motion; it may be worth noting, however, that Justice Rennie was the Justice who, soon after being appointed to the Bench by PM Harper a few years ago, almost immediately took a strict position on the current residency requirement in the Citizenship Act and ruled that the only correct standard is the actual physical presence test, going against three decades of case law allowing qualitative tests to be applied . . . in other words, Justice Rennie clearly comes from a school of thought which appears to be well within the PM's preferences.
As has been well noted in the forum, but as a reminder, the Galati challenge is not about the new residency requirements in the amended version of what will be, when in force, Section 5(1) of the Citizenship Act.
However, the challenge is not just about citizens born in Canada, but about dual citizens, whether they are a dual citizen by birth or as a result of naturalization.
Overall:
In any event, both the provisions governing the new residency requirement (including intent to continue residing in Canada) and the new grounds for revoking citizenship, will most likely come into force on the same date.
This is coming in 2015. And while we do not know for sure when, it is almost certain it will be by the 1st of October at the very latest, most likely by July 1st, and possibly earlier than that.
As of now, Galati's lawsuit does not preclude the coming into force of any provisions in Bill C-24. If the challenge is successful, it will only have an impact on the specific provisions governing the revocation of citizenship for dual citizens.
It is very unlikely that an application made by February 2015 will be affected by Bill C-24, or subject to the new residency requirement. Possible, but not at all likely.
The risk goes up each succeeding month. By mid-March, PRs on the cusp will want to seriously consider, if they meet the current residency requirement with a margin of at least a few days, getting the application sent off in time to arrive at CIC in Sydney by the 28th of the month, next to last day of the month at the latest, just in case the Governor in Council orders the provisions referenced in section 46(2) of Bill C-24 to come into force on the last day of the month or the first day of the next month.
For some it will be very, very close as the end of a respective month approaches, and some may be faced with deciding whether to apply based on exactly 1095 or 1096 days. Very tough decision for those who approach this threshold in March through May, given that it would be much better to have at least ten days margin or so, given the risk that waiting into the next month might miss beating the coming into force date for the new residency requirement. By June the pendulum swings heavily toward applying before the end of the month even if with a very minimal margin, the risk the change is coming being high.
Again, a lot of the anxiety can be eliminated if the government will only announce the date in advance. Cannot count on that happening.
